another stuttering problem but not your normal one

[mitch83]

I just bought a 95 AWD talon TSI and I took it on the highway it was driving fine when all of a sudden it started running like it was only running on 2-3 cylinders. If I let off the throttle it stops but as soon as I touch the throttle it just starts stuttering like crazy again like I said as if it is only running on 2-3 cylinders. If I stop and let it cool down a little it dosent do it but as soon as it warms up a bit boom it starts up again. So far I have only changed some vacum/boost hoses. From what I can see the only mods it has is a K&N filter,boost guage,crank case filter I changed the vacum lines today and started it up to let it idle it did fine the 1st couple times then it started idleing ruff eventually idleing so bad that it was barely staying started. I know I do have a small vacum leak coming from the sensor on the front side of the trottle body(I'm a newbie to DSM engines) I unplugged it and nothing happened I plugged it back in and it hesitated for a split second then went back to normal. Any suggestions I've searched this whole board for the answer but none of the ?s refect my problem 100%. If you need more info please ask thanks.

also before I had this problem as well as while i was driving with it occuring if I try to get on it my boost guage reads 10-13psi but it dosent fill like I'm even adding throttle the turbo just spools up and the boost guague rises but really no indication of added power or accelertion.

Check all of your intercooler conections and make sure the clamps are tight.

I'll give that a shot but what about the stumbling problem. I dont have an ohm meter to check the ISC or the power transistor but I plan to check them out.

stumbling/stuttering was oil on the plugs yaaaaaaahhh meeeeee.
